The inner planets are smaller than the outer planets. This may be because the outer planets are called gas giants. This means that gas can accumulate in size at times, and this can be one of the situations.
the outer planets are bigger than the inner planets
You could compare them by: * size * mass * volume * ability to support life * atmospheric features * diameter * surface features * temperature * etc.
The inner plants. The size and distance of the outer planets means they have longer and more spaced out orbits
They are small and have rocky surfaces.its there size and so is for outer planets
Inner and outer planets have some things that are in common but there mostly way different. For instants they both orbit the sun. On the other hand the outer planets are made mostly by gas, that's why they are called the gas giants. The inner planets are mostly made by rock and dust. The inner planets are called Terrestrial planets and the outer planets are called Jovian planets. The inner planets are closer to the sun, have more density, they have less moons, there about the size of Earth, and they rotate slowly. The outer planets (Jovian Planets) are farther from the sun, they have less density, they have more moons, they are large, about the size of Jupiter, they rotate rapidly, and they have more mass. These planets are alike because they both orbit the sun.
During my extensive travels, I noticed that all of the planets from Jupiter on out are bigger than any of the planets from Mars on in.
The four outer planets are all of the type astronomers call "gas giants", and have no hard, rocky surface per se. The inner planets are all solid rocky "terrestrial" planets. Also, the four outer planets are larger in size and lesser in density than the inner planets.
The orbits of the four inner planets are much closer, all orbiting the sun within ¼ billion km. The outer planets are more spread out, but are much larger in size. Their distances roughly double each time as you go out from Jupiter. Average distances of inner planets from sun; Mercury, 57,909,175km Venus, 108,208,930km Earth, 149,597,890km Mars, 227,936,640km Average distances of outer planets from sun; Jupiter, 778,412,010km Saturn, 1,426,725,400km Uranus, 2,870,972,200km Neptune, 4,498,252,900km
Eris is an OUTER planet. The only inner planets are mercury, venus, earth and mars. An outer planet is not related to the size of the planet but rather the distance from the sun.
Inner planets (inside the main asteroid belt) are "terrestrial", with a solid rocky outer crust above a rocky "mantle". The outer planets (beyond the asteroid belt) have no crust. Like the Sun, they are composed almost entirely of gas. The reason the gas planets became planets instead of stars was because of their small size.

Outer planets are made up of gas and dust particles, have thicker atmospheres and are bigger due to their place in orbit around the sun, while inner planets are mostly solid particles, warmer, and closer to the sun because of their gravitational attraction to it.
The average sizes of the outer planets are smallest than the average size of the Pluto so that they can called them the dwarf planets.
Each of the four inner planets have a clearly defined terrain. They are different to the gas planets, which don't have a clear solid surface. The inner planets are also much smaller and less massive, yet have a higher density than the outer planets. The inner planets have fewr moons due to their smaller mass and size. As they are closer to the sun, they orbit the sun in less time and are also warmer.

The Sun is huge it is bigger than all inner planets and probably the outer ones too.
Because the outer planets are gas giants except for Pluto. Pluto is an outer planet because it is the object (planet) that kept interfering with Neptune's orbit. Pluto is one on hundreds of thousands of meteoroids that a around the size of our moon.
The main differences between inner and outter planets are: Outter planets are all gas planets and are huge in size and have extreme heat temperatures, Inner planets all have a solid crusts, they are small in size and have lower temperatures than gas planets
The relative size of the gaseous atmosphere - mostly due to the amount of hydrogen in that atmosphere.
All four rocky planets are much smaller than gas planets.
The four inner planets in order of size from SMALLEST to LARGEST are Mercury, Mars, Venus, and Earth.
These are the "outer planets." They are outside the asteroid belt which seperates the outer and inner planets. The asteroid belt itself is believed to be another planet which was torn apart by Jupiter's gravitational pull. Lastly, all of the outer planets with the exception of Pluto are called gas giants due to the fact they do not have a solid rocky crust like the inner planets. Pluto has recently been downgraded from a planet due to its size as well as its odd orbit.
The four outer planets are all significantly larger than the four inner planets. Beyond that there's no simple relationship. The size of the planets (from smallest, 1, to largest, 8) in order of distance from the Sun: 1, 3, 4, 2, 8, 7 ... and then it gets vague. If you go by radius, the last two are 6, 5 and if you go by mass they're 5, 6 (either way, they're nearly twins).
Uranus and Neptune are roughly the same size.
